A leakage current has been detected by the inverter. This leakage current can be caused by an accumulation of leakage currents present in the building, added to those generated by the inverter, the solar panels and the battery.

It is necessary to check that the panels, inverter and battery are properly grounded. If leakage currents occur in the middle of the day, it is likely that they are coming from the solar panels, especially if this happens when the humidity level outside is high. In this case, it is necessary to identify the origin of this current leakage which generally comes from the connectors which are not perfectly waterproof.
